Is there an event I can fire when a bound datarepeater is completely done drawing?

Hi,

Wisej.NET doesn’t draw anything, ItemCloning is fires only when new items are cloned and that is only what’s needed for the view. You can have 1M items and 5 ItemCloning events if the DataRepeater only needs 5 panels.

HTH,

Alaa

I’m looking forward to this event too.

For now I use (might not be the best approach but works kinda):

Private Sub DataRepeater1_ItemCloning(sender As Object, e As DataRepeaterItemCloneEventArgs) Handles DataRepeater1.ItemCloning
If DataRepeater1.ShowLoader = False Then
DataRepeater1.ShowLoader = True
Application.Update(Me)
End If

End Sub

Private Sub DataRepeater1_ItemCloned(sender As Object, e As DataRepeaterItemEventArgs) Handles DataRepeater1.ItemCloned
DataRepeater1.ShowLoader = False
End Sub

There is no DataBindingComplete event like the DataGridView. The data binding is ongoing since it’s a completely virtual system: only the visible panels are created and then continually reused while the user scrolls. You can scroll 1M panels and the control only creates 5, for example. The data is always coming from the data source.

When a new panel is needed, there is the ItemCloning and ItemCloned event. If 5 items fits in the view + PrefetchItems  then you get 5 ItemCloned events only. When an item is populated with the data from the data source there is the ItemUpdate event. It fires everytime an item is updated from the data source. If you have 5 items in view and 1M rows then ItemUpdate is fired every time an item is reused. It is fired after the update so when you process that event the data in the controls is already correct.

You could handle the update cycle this way, override the DataRepeater in your class, say DataRepeaterEx:

protected override void OnWebEvent(WisejEventArgs e)
{
   if (e.Type == "update") {
     // updating items in view.
     base.OnWebEvent(e);
     // done updating items in view.
   }
 else{
   base.OnWebEvent(e);
 }
}

We may add an event for that actually, seems like a good thing to have.
